To address this natural change, the investigators propose secondary analyses with additional reference periods. Our first additional reference period for the randomized groups will be the O/E in the 6 months prior to CNH Dashboard implementation (months -6 to 0), which will be compared to the O/E of the primary analysis period. Second, we will examine the change O/E for the primary reference period. We will compare the O/E of randomized group 1 to the other randomized groups using Student's t-tests to determine if there has been significant baseline change over the course of the evaluation. Finally, the investigators will examine the O/E in the reference period as a function of time. This will particularly pertain to Groups 3 and 4 which have a longer window (12 and 15 months respectively) by which we can examine the temporal change in O/E without the intervention.
